要約(日本語): The connection of wind farm to the electricity grid is facing a new challenge: low voltage ride through capability. During a fault, the generator will accelerate because of the unbalance between the mechanical input power and its electrical output. Even after the grid recovers, the generator tends to slow down voltage restoration and this can lead to voltage and rotor speed instability.In this paper, a flywheel induction motor is proposed to maintain the generator stator voltage during the fault, thus improve the stability of the system. IThe flywheel induction motor is connected parelled to the wind turbine generator and it operates as a voltage stabilizer. Simulation results are given to prove the proposed method.
